Study Notes

Biogas Sources

Common sources of biogas include agricultural waste, sewage sludge, municipal solid waste, and food waste.

Biogas Uses

The primary use of biogas is as a fuel for electricity generation, cooking, and heating.

Biogas Composition

The main component of biogas is methane (CH4), typically making up 50-70% of the gas.
Carbon dioxide (CO2) is also a major component of biogas, typically making up 30-40% of the gas.
Other components of biogas include water vapor, hydrogen sulfide, and ammonia.

Biogas Components

Methane (CH4): a combustible and renewable energy source.
Carbon dioxide (CO2): a greenhouse gas that contributes to global warming.

Biogas Uses

Electricity generation: biogas is used to power generators and produce electricity.
Cooking: biogas is used as a fuel for cooking, replacing traditional fossil fuels.
Heating: biogas is used for space heating, water heating, and process heating.

Biogas Production Methods

Anaerobic digestion: a process in which microorganisms break down organic matter in the absence of oxygen, producing biogas.
Fermentation: a process in which microorganisms break down organic matter, producing biogas as a byproduct.
